About QRBarcoder

What We Do

QRBarcoder is a free, browser-based barcode and QR code generator. We support all major barcode formats — EAN-13, UPC-A, Code 128, Code 39, EAN-8, ISBN, PDF417, and Data Matrix — as well as fully customizable QR codes with color, size, and error correction options.

Everything runs directly in your browser. No account, no sign-up, no server processing — your data never leaves your device.

Who Uses This

QRBarcoder is used by small business owners creating product labels, developers testing barcode systems, publishers generating ISBN barcodes, logistics teams printing shipping labels, and anyone who needs a quick, reliable barcode without installing software.

Our Approach

We built QRBarcoder because existing tools were either slow, paywalled, or required accounts for basic functionality. Our goal is a single, fast, no-friction tool that works for every standard use case.

The barcode rendering uses bwip-js, a well-established open-source library that implements the full BWIPP barcode standard. QR code generation uses the qrcode library, compliant with ISO 18004.

Questions or Feedback?
